LAMP-BURNER.

Specification of Letters Patent.

Patented at... ca, iai.

Application filed September 30, 1916. Serial No. 123,179.

To all whom it may concern."

Be it known that 1, MICHAEL. Onos, a citizen of the United States, residing at Seattle, in the county of King'and State of Washington, have invented a new and useful Improvement in Lamp-Burners, of which the following is a specification.

This invention relates to improvements in lamp burners, and the object of this 1mprovement is to provide a cheap and simple burner for a signal lamp or lantern that will prevent the leakage of oil when the lamp is turned into inclined or inverted positions.

The invention consists in the novel construction of a lamp burner and in the adaptation and combination of parts, as will be more clearly hereinafter described and claimed.

In certain kinds of work, particularly in railroading, a great deal of signaling is done with signal lamps, and this signaling necessitates the lamp'being frequently turned into inclined or inverted positions, thus causing the oil to tend to flow outwardly through the burner andrun down over the sides of the lamp. The same condition is often present where the lamp is carried upon the arm of the user, as is done in certain kinds of work in railroad yards and similar places.

In the construction of lamp burners it is customary to leave a vent hole therein which communicates either directly or indirectly with the oil cup of the lamp to admit air and equalize the pressure within the'oil cup as the oil is removed therefrom and in the burners now in common use on signal lamps, when the lamp is turned into an inclined or inverted position, the oil in the oil cup oozes out through this vent hole and around the wick, and runsdown over the sides of the lamp, thus not only wasting oil but greasing and soiling the clothes of the workmen, the iioors on which the lamp is set, and everything else with which the lamp comes in contact.

This burner is designed to prevent the leakage of oil in the manner above described,

thus eflecting a saving in the amount of oil.

consumed and a greater saving in the clothing of workmen who are obliged to use signal lamps. o n

In the drawings, Figure 1 is a view in side elevation of a burner constructed in accordshowing an oil cup in cross section; Fig. 2 is a view in vertical teriorly section on broken line 2, 2 of Fig. 1; Fig. 3 is a plan view of the view in cross section on broken line 4, 4. of Fig. 2: Fig. 5 is a view in cross section illustrating the burner as it may appear when the lamp is turned into an inclined position; Fig. 6 is a fragmentary cross sectional view of the burner as it may appear when the lamp is inverted; and Fig. 7 is a fragmentary view in cross section, illustrating a slightly modified. form of the device.

teferring to the drawings throughout which like referencenumerals indicate like parts, the numeral 10 indicates a cylindrical V casing that incloses a chamber, 11, and forms the base portion of my burner, the lower end of such casing preferably being exthreaded, as at 12, to adapt it to be screwed into the neck of an oil cup, 13, as shown in Figs. 1 and 5.

14 is another casing casing 10 and secured thereto to form an overflow chamber, 15, for oil, the top of the casing 14 preferably having a convex central portion, 16, a depressed annular trough-like portion, 17, and raised edges, 18, for purposes hereinafter explained.

20 is a wick guide that extends upwardly through the casing 10, and terminates within the overflow oil chamber and 21 is another wick guide that extends downwardly through the top of the casing 14 and terminates within the chamber 15 at a point slightly above the top of the wick guide 20. The bottom end of the wick guide 21 is erably flared slightly, as indicated at 22, to facilitate the insertion of a wick, 23, although this feature is not essential.

24 are spur wheels that are mounted on a spindle, 25, and project through slots, 26, in the sides of the wick guide in a well known manner so that they will engage with the wick and move it up or down within the wick guides. The spindle, 25, projects outwardly through the side of the casing 10, and which it may be turned.
